Q: Do I need to upgrade to the latest 16-bit version of and if so - why?
A: If you already have a 16-bit version installed (2.7 or less) - Yes. The software undergoes many enhancements and developments and new functionality is introduced with every new version. Many market-driven requests are introduced as standard features for the benefit of all users. Older versions become obsolete and are longer supported.
Q: How do I upgrade my version and is the upgrade free?

To upgrade your version of , contact your Distributor with your Version and License Details([8 digit number] which can be found on the Help About window).
Q: What kind of maps can be used by the system?
A: A variety of image formats are supported.
The 16-bit version supports the following:
BMP - Windows Bitmap
PCX - Zsoft Painntbrush
IGF - Internav Graphic File
TIF - Tagged Image File Format
TGA - Truevision Targa
JPG - JPEG File Interchange Format
GIF - Compuserve
DIB - Windows Device Independent Bitmap
Various color depths are allowed (16 colours to High Colour). The suggested resolution to use when scanning maps is 150-200 dpi (dots-per-inch). The most popular are BMP, JPG, TIF and PCX, however, the 16-bit version does not support handling of very large image files (10Mbytes and over).

The 32-bit version supports the following:
BMP - Windows Bitmap
DIB - Windows Device Independent Bitmap
BIL - Band Interleaved By Line
BIP - Band Interleaved By Pixel
BSQ - Band Sequential
SUN, RS, RAS - SunRaster
TIF - Tagged Image File Format
JPG - JPEG File Interchange Format
The 32-bit version allows to load large image files (single files 150Mbytes and over).


Q: How are the maps or images geo-referenced (registered)?
A: The software has an Image Registration option, which allows to register (geo-reference) maps using 2 or 4 known points on the map. These points should be located as far from each other as possible (on a diagonal for 2 points) and are defined by assigning either Latitude/Longitude or Easting/Northing (AMG - Australian Mapping Grid) co-ordinates.
Q: How frequently can a vehicle position be updated on the screen?
A: This is dependant on the type of communications used. Where dial-up and modem handshaking is involved (GSM Data modem, Satellite phone) the connection may take approx. 20 seconds (3 positions per minute), SMS faster; where HF radio is involved it may take closer to 2 positions per minute; where VHF/UHF radio is involved position updated can be received approx. every 2 seconds, which results in around 30 position updated per minute.
The vehicle update frequency can only be as fast as allowed by the communications carrier, therefore selecting the right type of communications for a specific application is the primary consideration.
Q: How far back can vehicle activities/movements be viewed and re-analysed?
A: There is no limitation on how far back tracking data can be recalled. The selection of vehicle activities is made from a calendar-style selection menu, which allows to select the year, month and day. The days on which the tracking system was operational are shown in bold. An additional choice time of day and vehicle ID is available.
Q: Can the system be scheduled to operate at pre-defined times?
A: Yes. There are two different methods available and they are applicable to vehicle groups not individual vehicles. The first method involves specifying an automatic tracking start and stop time for each vehicle group. This will poll all selected vehicles continuously for the duration of the start/stop period at the specified polling interval. The second method allows to specify up to 5 polling times for each group at which the system will poll all selected vehicles once and update their positions.
